Game Post Sleeves are inserts for concrete footings to hold and secure posts. Sleeves are available for Basketball, Tennis, Tetherball, and Volleyball posts and are provided with or without a cap. The caps are used to help keep dirt and debris out of the sleeves when posts are temporarily removed. Caps are available in 4 versions: “without a cap”, “hinged cap”, “brass screw cap”, or “neoprene cap”. Model numbers reflect single sleeve pricing.
